2. A priority encoder circuit has four inputs, x3, x2, xl, and x0. The circuit has three outputs: z, yl, and yo. If at least one of the inputs is 1, z is 1 and yl and y0 represent a 2-bit, binary number whose value equals th ndex of the highest numbered input that is 1. E.g. if x2 is 1 and x3 is 0, then the outputs are z = 1 and yl 1 and yo = 0. If all inputs are 0, z = 0 and y1 and yo are dont-cares. Using (a) List in decimal form the minterms and dont care minterms of (b) List in decimal form the maxterms and dont care maxterms of k-maps each output. each output
